METAL BEENFOBGED-GOITCRETE R'AXLWAY TIE.

Application filed August 8, 1924. Serial No. 7311,8-79.

Minneapolis, in the county of Hennepin and State of Minnesota, haveinvented certain new and useful Improvements in MetalReenforced-Concrete Railway Ties; and I do hereby declare thetfollowingto be a full, clear, and kexact description of thel invention, such aswill enable others skilled in the art to which it appertains to make andusethe saine. l

My present invention has for its object to provide a strong, durable,and highlyefticient metal reenforced concrete railway tie, and to thisend it'consists of the novel devices and combinations of deviceshereinafter described and defined in the claims.

In the accompanying drawings, which illustrate the invention, likecharacters indicate like parts throughout the several views.

Referring to the drawings: y

Fig. 2 is a longitudinal section taken on the line 2 2 of Fig. 1;

Fig. 3 is a horizontal section taken on the line 3 3 of Fig. 2;

Fig. 4 is a View partly in 'elevation and partly in transverse verticalsection taken on the line 4 4 of Fig. 2, on an enlarged' scale;

rEhe numeral 8 indicates the concrete body of a railway tie, and thenumeral9 k indicates sections of a pair of rails supported thereon.VEmbedded in the body 8 is :a metal reinforcement comprising a pair ofparallel longitudinal tie bars Y10, a pair oftie bars 11, a truss rod12,anda reinforcement 18 of expandedmetal. The' parallel end tie bars 10and 11 are inyoblique arrangement with the ends of the tie bars 11resting on the tie bars 10, and which tie bars are thusV connected .byfour upright sleeves 14 which extend through aligned bores therein. v l

The end bars 11`are turned in respect to the body 8 so that they extendobliquely thereacross and thereby position the sleeves 14 in pairs andwith the sleeves of each pair spaced both longitudinally andtransversely in respect to the body 8. The truss rod 12 extends belowthe tiey bars 10 and 11 and diagonally between the two outermost sleeves14, and has in its ends bores through which the respective sleevesproject. The tie bars 10 and 11 and truss rod 12 are supported fromshoulders 15 on the sleeves 14, and which shoulders are in the form ofnuts screwed onto said sleeves from the upper ends thereof and supportthe ends of the tie bars 10 and 11 and truss rod 12 at a point justslightly above the vertical center of the body 8.

The reinforcement 13 extends above the tie bars 10 and 11 and outwardthereof, and parallel to the top and sides of the body 8 and is locatedsubstantially midway between said tie bars and the top and side faces ofthe body 8. This reinforcement 13 is supported on thiinbles 16telescoped onto the sleeves 14 which rest on the end bars 11. Nuts 17are screwed onto the upper end of the sleeves l14 land cla-mp thereinforcement 13 thereon and the sleeves onto the tie bars 11. On thelower ends of the sleeves 14 are heads 18 recessed to receive the headsof anchor bolts, as will presently appear.

The tie bars 10 and 11 are iiat, and the tie bars 10 aretwisted betweenthev sleeves 14 to increase their hold in the-cement and thereby moresecurely hold said sleeves against longitudinal movement in respect tothe body 8. It will be noted that the ends of the sleeves 14 andthenbent laterally downward at 19 to further increase their 4holdin thebody 8.` By reference to Fig. 2

it will be noted that the longitudinal center of the truss rod 12 isonly slightly above the bottom face of the body 8 and from this pointvthe end portions thereof diverge up- Vward tothe sleeves 14 to whichthey are at beveled to rest Adirectly thereof. .The metal reinforcement13 eX- tends substantially the full length oli the body 8. It Will benoted that the improved railway tie has no projection whatsoevervplates-may be easilyl replaced trom timerto time' or a number thereot1used to levelup a rail. These plates 22 "have bores aligned with thebores inthe'sleeves 14- andthe anchor bolts 20 extend'upwardthroughisaid sleeves and bores 1in the pla-te 22 with? their headsseated in the'recessedfheads-l8 of said sleeves which hold `:said bolts`1from turning.
